Description

Overspeed prevention jaw for road installation}

The present invention relates to a speed bump for road laying, and in particular, to provide a speed bump for road laying, characterized in that the laying by connecting a synthetic resin molded uneven structure to the road.

The speed bumps laid on the road are arc-shaped, trapezoidal, and speed bumps by shape, but the most versatile and proven field performance is arc-type speed bumps. The upper surface of the circular arc speed preventing jaw is a circular arc or parabolic curved surface, and the circular arc speed bumps in the present invention as a symmetrical shape means such a bump. The arc-shaped speed bumps are evaluated by vertical acceleration and stability, which are the physical evaluation items for each experiment speed.The installation length is 3.6m, the installation height is 10cm, and the curved shape is divided into four equal lengths of 1/4, 2/4, 3 7.7cm, 10cm, and 7.7cm are approximated at / 4 points. However, on local roads of less than 6m in width, the speed bumps are reasonable at 2m in length and 7.5cm in height, in which case the curved shape is 5.8cm and 7.5 at 1/4, 2/4, and 3/4 of the installation length, respectively. cm. It is the shape that connected 5.8cm by approximation curve.

In order to give sufficient visibility to the speed bumps, white and yellow reflective paints should be painted according to the road marking color standards of traffic safety facilities (Korean Industrial Standard KS M 5322, KS M 5333, KS M 5336). The color considers the color contrast taking into account the brightness of the pavement surface.

The installation location of the anti-speed jaw is within 30m from the intersection of the intersection and the road, within 30m from the end of the road concave termination curve, within 20m from the point of maximum gradient change (when more than 10% slope) and other traffic safety is recognized as necessary. The location where the speed bumps are prohibited is within 15m from the intersection, within 20m from the crossing, within 20m from the bus stop, where the entrance of the year is obstructed, such as bridges, underground roads, tunnels, and dark places. It is a place to disturb.

As a speed limiting jaw for conventional road laying, Utility Model Publication No. 1994-6280 has an overspeed preventing protrusion of an automobile, and has both an upper and lower curved curved surface, an insertion fixing protrusion having a crystal lens fixed to an insertion groove of the curved surface, and a central lower uneven portion, and both round surfaces. It is a speeding prevention device that constitutes a groove on the opposite side and a projection on the one side of the center, and these devices have a low vertical acceleration, which is a physical evaluation item, and can be laid on the road only when excavating a trench for laying a fixed protrusion on the road. Since the curved surface is easily damaged by friction with the car tires and the crystal lens is inserted into the curved surface, the reflectivity of the headlights of the car is weak and the visibility is poor.

The prior art speed bumps of the Korean Utility Model Registration No. 152834 are related to the speed bumps that are easy to install and dismantle, made of rubber, etc., and are made of a central assembly and both ends of the assembly, and the curved surface of the assembly is elliptical. It is formed, and the connection part of the assembly member is configured to be fitted into the fitting groove and the fitting frame, the edges of both ends of the assembly member is fixed with an anchor bolt, showing a configuration that is attached to the front and rear surfaces of the assembly member, but cited above As the speed bumps are assembled with fitting grooves and fitting frames of the assembly members, the assembly and assembly are not simple. Especially, if the vehicle is loaded after assembly, the fitting frames and fitting grooves of the connecting parts are first broken, which disturbs the road. The service life of the speed bumps is very short, and the number of fastening assembly parts on the road can be fixed. Since anchor bolts can be fixed only to the projections at both ends of the assembly, the bearing capacity is very weak as a whole, and the light reflector is attached to the front and rear surfaces of the unit without considering the light reflection angle. Sinan Publication No. 20-1993-2778 The prefabricated speed bumps for roads consist of a plurality of humps by dividing the speed bumps, each of which is divided into a middle plate and two inclined plates, and forms a arm that fits to the division surface. The irregular surface is formed obliquely on the upper surface of the plate and the two inclined plates to apply yellow luminous paint on the concave surface, and the bolt plate is drilled at the end of the middle plate and the inclined plate and the end of the inclined plate. The end of the center plate is joined to the lower side of the end of the inclined plate, and the top surface of the hump forms a checkerboard irregularity surface. Road speed bumps coated with yellow luminous paint on the road, and the speed bumps are divided into two parts, where the middle plate and the two inclined plates are joined to each other, making the production complex and vulnerable to large loads of the car. It did not have the durability as a back road fixture,

Conventional Utility Model Publication No. 20-1998-14920 The factory factory of the speed preventing convex and concave block on the road injection molding in the form of a speed preventing concave and convex block, and to be installed prefabricated on the road to install the speed preventing concave and convex block, A fastening hole formed with a stepped jaw is formed on the edge of the block, and the anchor bolt matching the fastening hole is fixed on the road so that the anchor bolt is placed in the fastening hole when the uneven speed block for speeding is placed on the road. As a construction device of the uneven block for speed prevention of the fixed road, it can be used immediately after laying on the site and can be moved to a place. However, the most important physical evaluation items are the low vertical acceleration and poor construction. It was.

The present invention has excellent visibility in providing a speed bump installed by a dry laying method, and can improve the aesthetics of a city by being beautiful, and can be laid in an arbitrary length according to the road width. The purpose is to provide speeding bumps for road laying that maximize the visibility by providing high efficiency, preventing premature damage of connecting parts, firm supporting capacity as road facilities, and installing light reflectors at headlights and light reflecting angles.
